Taking steps to bring the process to a safe state, provides an improved level of
safety when power supplies, communication links or parts of the control system
fail. Such steps may require, for example, the installation of valves or relays that
automatically return to a fail-safe position.
Product Safety
The following safety rules must be observed at all times:
• To avoid discharging static electricity, ground both yourself and any tools
before handling printed circuit boards, batteries, memory cards, and other
sensitive pieces of the equipment
• All electronic devices are sensitive to ESD (electrostatic discharge). To
avoid accidental damage while handling printed circuit boards, it is
recommended to wear a wrist strap, grounded to the chassis. The strap must
have a built-in protective resistor
• Anti-static, conductive plastic bags must be used for storage and transport
of PC boards in transit.

Safety Summary
Before replacing Units
Maintenance
All procedures for replacing units can be located by referring to the relevant
documentation.
Removing or replacing units with system power connected can cause injury to
personnel and damage to equipment. It is, therefore, of the utmost importance
that the power supply be fully disconnected, on the process side, before removal
or insertion of units takes place.
See Online Replacement of Unit on page 198 and I/O documentation.
It is recommended that a stock of suitable spare components be maintained to
avoid system downtime.
Ensure that back-up copies of the current application program are made at
regular, predetermined intervals to avoid system downtime.

Safety Summary (continued)
Operating Environment
Before the AC 800M Controller system is brought online, investigate which
environmental conditions are applicable. Take note in particular of the
following:
• The controller must not be exposed to conditions that exceed the values given
in the relevant technical specifications.
• The controller must not be used in an environment exposed to strong electrical
interference. Electrical machines can produce interference that exceeds levels
permitted for the equipment, for example during repair work.
• All products must be handled with appropriate precautions with regard to
electrostatic damage.
• The controller must not be exposed to direct sunlight.
Important Software Check
• Use the system’s fault-monitoring facilities to prevent accidents or mishaps.
• When in doubt, ALWAYS CHECK before executing changes.
Important Hardware Notice
• DO NOT, under any circumstances, disconnect the power supply to a
normally functioning system. Always use the correct system shut-down
procedure prior to disconnecting the power supply.
Signal Noise Due to Cables
Cables which may cause electrical interference (for example, power supply cables)
must not be installed adjacent to bus cables carrying fast digital signals. Ensure that
a minimum distance of 10 cm (4 in.) is provided between cables installed inside
cabinets.
Hazardous Electrical Supplies
Operational and maintenance procedures, during which personnel may come into
contact with high voltage, should only be carried out by personnel fully trained in
the maintenance of electrical equipment within those environments, and who are
fully aware of all risks involved.
